This usb mic offers great portability and ease of use. It's literally plug and play and the sound quality is decent. It's main drawback is latency--the delay between the vocal/instrument sound and the time when that sound reaches the headphones. If you are using Garageband with the suggested RAM, processor speed, and OS, the sound through headphones plugged into the computer resembles a tin can effect. It's not horrible, but it is distracting. You can still record and even multitrack, but be prepared. The "pristine" sound of the Mic 96K only appears on the recorded track, not the headphone monitor. There are two main consequences to this issue. First, it's a little hard to mic an acoustic guitar while trying to find the "sweet spot" where the Mic 96k works best. You can place the mic in several different locations, but the tin can sound makes mic placement difficult. Second, because there is a delay between playing the sound and hearing it, there is some worry that multiple overdubs won't sync perfectly. The delay is only milliseconds and perhaps I'm a little paranoid, but it may be detectable to a trained ear.
Of course, there are some solutions to this basic problem, including more RAM, more processor speed, and software that allows the user to adjust the buffer size. When I talked to tech support at Apogee, they suggested an upgrade to Logic Pro X. Logic allows the user to adjust buffer size and reduce latency. This feature does not exist in Garageband, although it did on previous versions of Gargeband. Thanks, Apple!
On the other hand, who wants to spend an additional $200 (on top of the $200 plus for the mic itself) just to cure a deficit in sound quality? Who wants to upgrade there Mac OS just to buy Logic, which only works with OS 10.9? Who wants to add RAM or even upgrade to a new desktop or laptop with a faster processor? Not me. Apogee should be more up front with this issue. The truth of the matter is that Mic 96k may work well with some set ups, but it has issues. Apogee oversells the pristine quality of the mic and it's workability with Grageband. So, as always, buyer beware.
